Description

Bis(2-Butoxyethyl) Phthalate-D4 is a deuterated analog of the common plasticizer bis(2-butoxyethyl) phthalate, where four hydrogen atoms are replaced with deuterium, making it a valuable internal standard for analytical chemistry. This high-purity, isotopically labeled compound is essential for ensuring accurate quantification and method validation in sensitive analytical techniques. It is primarily needed by analytical laboratories, environmental testing facilities, and chemical manufacturers engaged in trace-level analysis of phthalates and related compounds.

Application

• Primary use as an internal standard for Gas Chromatography-Mass Spectrometry (GC-MS) and Liquid Chromatography-Mass Spectrometry (LC-MS) analysis of phthalate esters.
• Critical component in method development and validation for regulatory compliance testing (e.g., EPA, REACH, RoHS) targeting phthalate content.
• Enables precise quantitative analysis in complex matrices such as polymers, consumer products, and environmental samples.
• Used in deuterium dilution studies and metabolic pathway research within academic and industrial R&D settings.
• Supports quality control and assurance protocols in industries monitoring phthalate migration, including food packaging, medical devices, and toys.
• Facilitates forensic and environmental analysis for tracing and quantifying phthalate contamination.
